Re: [Sip] international chars in hostname part of SIP URL

As I understand it, the restriction if for conformance with DNS,  which is
what translates those hostnames into IP addresses.  For example, the "_"
character (underscore) has historically been invalid in DNS. It's only
recently appeared as a valid restricted character for delimiting protocol
names in SRV records.

There's probably ongoing work on internationalizaing DNS, but it's not going
to be easy.
